There have been several world class Australian bodybuilders. None have won the Mr Olympia but perhaps Bev Francis should have won the Ms Olympia many times.
Peter McCarthy, Adrian Batho, Dan Mahoney, Luke Wood, Lee Priest, John Terilli, Roger Walker, Frank Colombera, Terry Mitsos, Les Spendlove, Guy Grundy, Sonny Schmidt, and many others. Some won the NABBA Mr Universe like Terilli and others won international titles like Walker and McCarthy. Lots of talent downunder.
